Abstract

PURPOSE: To enable control of quick response in a wide range, by separately instructing a component of a stator current in the same direction as a magnetic field and another component perpendicular thereto and supplying the current components from separate power converters.
CONSTITUTION: A magnetic field detector 4 comprising Hall elements 41a, 41b and a vector analyzer 42 is provided. A calculation circuit 51 comprising multipliers 511∼514 and a polarity inversion amplifier 515 is provided to transform coordinates. Phase number converters 52A, 52B and the power converters 2A, 2B are provided further. The component iM1 of the stator current of an induction machine in the same direction as the magnetic field and the other component iT1 perpendicular thereto are separately instructed. The current components are supplied from the separate power converters 2A, 2B. The stator current is synthesized from the output currents iM1, iT1 of the separate power conveter verters. The output currents can be varied with quick response independently of each other although the phase angles of the currents cannot be sharply changed. Therefore, the stator current can be quickly altered.
